While noting that globally GM puts more than one million diesel engines into cars and light trucks, the company has “temporarily tabled” its US 4.5-liter Tier 2 Bin 5 diesel engine (earlier post) program for now, said Dan Hancock, GM Powertrain Vice President Global Engineering in remarks at the opening panel session of the DEER 2009 conference in Dearborn, Michigan.
Hancock said the company made the decision based on the changing scenario of fuel prices and capital constraints. GM has not, he was careful to note, cancelled the engine, which is “ready to go”.
Hancock also said that GM was continuing to work aggressively on its gasoline HCCI engine development (earlier post) and was continuing its work on fuel cell vehicles. Hancock noted that the relative emphasis GM places on different elements of its powertrain portfolio does get influenced by the amount of support shown, infrastructure requirements and so on.
“Right now we are continuing to support our fuel cell program,” Hancock said. The company is looking for developing commercial systems with support from private sector and government partners in the 2016 timeframe, he said.
